SC 4812T CDMA BTS Optimization/ATP
Transmit (TX) Path Audit
Perform the calibration audit of the TX paths of all equipped BBX2
slots, per the procedure in Table 3-35
Before installing any test equipment directly to any TX
OUT connector, first verify there are no CDMA BBX2
channels keyed. Failure to do so can result in serious
personal injury and/or equipment damage.
WARNING
If a successful All Cal/Audit was completed, this
procedure does not need to be performed, as BLO is
downloaded as part of the All Cal/Audit.
NOTE
TX Audit Test
The Tests menu item, TX Audit, performs the TX BLO Audit test for a
BBX2(s). All measurements are made through the appropriate TX output
connector using the calibrated TX cable setup.
